To increase the speed (by button)

Push the “RES/ACC” button and hold it until the vehicle reaches the desired speed. Then, release the button. The vehicle speed at that moment will be memorized and treated as the new set speed.

When the difference between the actual vehicle speed and the set speed is less than 4 mph (6.8 km/h), the set speed can be increased 1 mph (1.6 km/h) each time by pressing the “RES/ACC” button quickly.
